You may experience issues when using Qlik GeoAnalytics Connector due to TLS 1.2 not being enabled.
The following error can be seen in the log file C:\ProgramData\QlikTech\Custom Data\IdevioGeoAnalyticsConnector\Log\StackTrace.txt
System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Environment:
Qlik GeoAnalytics
The issue is due to the site https://ga.qlik.com no longer allows connections using TLS 1.0 and TLS 1.1, but only supports TLS 1.2 as part of security requirements.
To solve the issue do one of the following:
- Upgrade to .NET 4.6 or newer. TLS 1.2 should then be enabled by default.
- Make sure that you have a version of .NET that supports TLS 1.2, see https://docs.microsoft.com/en-us/configmgr/core/plan-design/security/enable-tls-1-2#update-net-frame..., then update the connector to the February 2018 version or newer.
